Application filed July 13, 1916. Serial No. 109,119.

To all whom it may concern:

Be it known that T, Gnonon H. Time, a citizen of the United States, anda resident of Anderson, in the county of Madison and State of Indiana,have invented certain new and useful Improvements in Heating- Stoves;and I do hereby declare the following to be a full, clear, and 6313C;description of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to improvements in heating stoves and moreparticularly to such as are intended to burn gaseous fuelone object ofthe invention being to so construct a heating stove as to enhance itscapacity to heat the air passing through the same and to increase itsgeneral efliciency to a maximum extent.

With this and other objects in view, the invention consists in certainnovel features of construction and combinations of parts as hereinafterset forth and pointed out in the claims.

In the accompanying drawings; Figure 1 is a vertical sectional view of astove embodying my improvements; Fig. 2 is a hori zontal sectional view,and Fig. 3 is a separate view of one of the internal radiator units.

1 represents a hollow base casting which may be supported on legs 2 andprovided with an open-work bottom or grating 8. The main drum or casing4 of the stove is mounted upon the hollow base 1, and a. tube orcylinder 5 is located centrally within the base 1 and is open at bothends, said tube or cylinder being mounted upon the bottom grating 3 andextending approximately to the horizontal plane of the top of the hollowbase.

A conical drum 6 is disposed centrally within the casing 4: and itsupper open end is supported by the top member 7 of said casing thesmaller lower end of said conical drum projecting into the open upperend of the tube or cylinder 5. A se 'mental disk 8 is disposed betweenthe conical drum and the outer casing a comparatively short dis tancebelow the upper end of both, and this disk is provided with a verticalflange 9 which projects upwardly above the plane of the flue opening 10in the back of the casing tion mixed 4, so that products of combustionmixed with air may be caused to flow to the top of the stove in front ofthe flange 9 and then downwardly to the flue opening at the back of thestove.

Radiator inembers 11 are located within the casing and disposed so as toproject alternately from diametrically opposite portions of the casing4, said radiator members being perforated to permit the passage throughthem of the vertical conical drum 6, and thus a worm or spiral passage12 is formed for the passage of products of combustion from burners 13located within the base l at respective sides of the tube or cylinder 5.

Each radiator member 11 is made hollow and may conveniently consist of asheet of metal cut in pro-per shape and bent or folded upon itself toform upper and lower parallel walls spaced apart to provide a chamber orpocket 14 between them. The free edges of each folded radiator memberare fitted snugly to the inner face of the casing l, and the latter may,if desired, be provided with grooves 15 to receive the edges of theradiator members.

The outer drum or casing l is provided with perforations 16 so arrangedas to communicate with the pockets of the radiator members, and theconical drum 6 is also perforated, as at 17, so as to communicate withthe radiator pockets.

From the construction and arrangement of parts as above described, itwill be seen that during the circuitous passage through the stove of theheated products of combuswith air, the air passing upwardly through thetube or cylinder 5 and conical drum 6 will be heated and this heated airwill escape into the room from the upper end of said conical drum. Theheating of air escaping from the conical drum will be augmented andintensified by the passage of air through the hollow radiator members inwhich the air will absorb heat-from the walls of said members anddischarge it into the conical drum.

My improvements insure effectual heating and circulation of the air, andthe stove will also effectually heat the surrounding air by radiation.

Slight changes might be made in the details of construction of myinvention without departing from the spirit thereof Or limiting itsscope and hence I do not wish to restrict myself to the precisedetails-herein set forth.

Having fully described my invention what I claim as new and desire tosecure by Letters-Patent, is

1. In a stove, the combination with a ver tical outer drum and avertical inner drum open from end to end, of a plurality of hollowdeflecting radiator members disposed between said drums andcommunicating with the outer air and the inner drum.

2. Ina stove, the combination of a vertical outer drum havingperforations; a plurality of hollow deflecting and radiator memberstherein formingpockets in line withthe perforations in the outer drum, a

vertical inner drum open from end to end and passing through the hollowdeflecting and radiatonmembers and communicating with the'pocketsthereln, and heatmg means below and in communication with said outerdrum.

3. In a stove, the combination with a base, a vertical outer drummounted thereon, and heating means within said base, of a plurality ofhollow deflecting and radiator members alternating from diametricallyopposite positions of the outer drum and communicating with the outerair, and a vertical conical inner drum open from end to end and passingthrough said deflecting and radiator members and communicatingtherewith, said defiectingand radiator'members' and conical drum forminga worm passage for products of combustion.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.

GEORGE H. KING.
